Q1: The value of momentum correction factor (β) for a laminar flow through a circular pipe, is

ANS:D - 4/3

The value of the momentum correction factor (β) for laminar flow through a circular pipe is: β=4/3​ This correction factor accounts for the variation in the velocity profile across the cross-section of the pipe. In laminar flow, the velocity profile is parabolic, and the maximum velocity occurs at the center of the pipe, with decreasing velocities toward the pipe walls. The correction factor β adjusts the theoretical momentum equation to better match experimental results. For laminar flow, the value of β is empirically determined to be 4/3​. Therefore, the correct answer is 4/3.
